| Title | Portable Density Guage Run Over |
| Event Description | The following was received from the State of Washington via email:
On Monday, November 30, 2020, at a construction site at 2800 MLK Jr South, Seattle, WA, a density gauge was run over by a mini dozer. The source was extended and in use at the time. When the device was run over, the handle that is used to extend and retract the source rod broke off from the gauge completely, leading to concern that the source rod had also broken off. Personnel on site were evacuated and the area secured. Because of the concern that the source rod had broken off, it was necessary to wait until a licensed entity that had the ability to handle the unshielded source arrived on site to continue recovery operations. Also, shortly after the incident, Northwest Technical Services (NTS), was hired for remedial action. When NTS personnel arrived, they were able to determine that the source rod had not detached as feared. A leak test to check the integrity of the source revealed no leakage and the source rod was able to be retracted back into the shielded gauge. Radiation readings and additional leak tests in the area were conducted to ensure there were no remaining safety concerns. There were none. The damaged source was taken to Northwest Technical Services in Snohomish, WA and has been secured while awaiting disposal. Washington Incident Number: WA-20-026. |
